LA6586FA数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The LA6586FA is Single-phase bipolar fan motor is put into silent driving by means of BTL output linear drive, offering high efficiency and power saving by suppressing the reactive current. Lock protection and rotation signal (FG, RD) circuits are built in, ensuring optimum application to small fans for notebook PC, consumer equipment power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.

特性 Features

• Single-phase full-wave linear drive by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
• Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
• Low saturation output (Upper + lower saturation voltage : Vosat (total)=1.2Vtyp, IO=200mA)
• Built-in lock protection and automatic reset circuits
• Built-in FG & RD outputs
• Built-in Hall bias (VHB=1.3V)
• Thermal protection circuit
• Extra-small package (Micro10)

应用 Application

• Consumer equipment power supply
• Car audio system
• CPU cooling system
• White goods
• Car audio
• Notebook PC

简介

LA6586FA属于集成电路（IC）的全半桥驱动器。由制造生产的LA6586FA全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
